Good stuff! Im really considering this. But do you "crash" when it wears off? I hate how i used to feel when ephedrine would wear off. I only dink coffe or rockstar in morning. I do worry about falling asleep. How did you get it prescibed? I sleep like shit and am going for apnea tests. But i did read that in studies monkees loved the provigil like coke!! Thanks for info!!
